Rock-art has been discovered and recorded in forty sites in northeastern Guanajuato, Mexico, as part of an ongoing project carried out by researchers from the National Institute of Anthropology and History. The majority of the images were created by hunter-gatherers who occupied the area during the 1-5 centuries AD, but religious iconography and inscriptions were also discovered dating to the colonial era, as well as the 19th and early 20th centuries.

A roughly 1,000-year-old Maya sarcophagus, vestiges of an extinct tribe, the oldest tomb in Mesoamerica, dinosaur fossils and human remains dating from the early 8th century are some of the most noteworthy archaeological finds made in Mexico during 2010.

Today’s tax codes are complicated, but the ancient Aztecs likely shared your pain. To measure tracts of taxable land, Aztec mathematicians had to develop their own specialized arithmetic, which has only now been decoded.

James O’Kon is using modern technology and forensic engineering techniques to uncover the mysteries of a vanished Mayan civilization. It began with a pile of rocks in the middle of the Usumacinta River deep in the rain forest between Mexico and Guatemala-the site of an ancient Mayan kingdom,

The grisly find of the buried bones of 24 pre-Hispanic Mexican children may be the first evidence that the ancient Toltec civilization sacrificed children, an archeologist studying the remains said on Monday.
